>>>>>If anyone sees a bunch and snaps up an extra I would be interested in buying it.
Scaru, I would have mailed one to you, but I just went back and the other two, they be gone now. Sorry.
Guy I talked with in garden dept said some guy came right in after me and bought the other two.
Another BLFer living very close to me where I’m staying in the OC, Calif.? Probably not. Probably someone who saw it on fatwallet. Fat wallet people buy a lot of these sale items and resell em on flea bay.
So we are not the only ones who know about it, so if you want one, might be best to grab one or two. You can always return it to HD months after you buy it.
As for using these in lights? I have NOT used the Sanyo tool 1500 mah cells. I have used the Sony and Samsung ones, which seem to work on par with “normal” 2600 cells, BUT YMMV. I did NOT do scientific comparison tests.
Has anyone done any real tests on any 1500-mah tool cells? Am I the only one on BLF who has used them? That’s hard to believe.
im almost thinking about cleaning off the useless bits of plastic to smoothen them up and i have two 10x18650 holders
most were 3.6-3.61v, one was 3.47v, a couple in the 3.55-3.59v range. as long as they are a decent cell… who can complain about $2.30 a cell??
edit: but i like your 3.6-3.65v range better than mine
>>>>>im almost thinking about cleaning off the useless bits of plastic to smoothen them up and i have two 10×18650 holders
Sounds like an idea!!! Didn’t think of that.
Usually the holders are open-topped trays, where the cells lie length wise. First one I’ve seen where they are enclosed like this.
The trays are really handy for stacking the batteries so you can take a bunch of DMM readings on the cells without having them roll all over the place.
Some super use will probably come to you for this cage thingie. Don’t be like me and throw it away … Then 3 days later realize the perfect use. Done that countless times.
thats how i measured mine. loaded them all in one half, and tested away. will be a project for another day, but saving them. keep one on the shelf by the light stash, and one by the charger maybe for depleted cells
also saved the life meter from it haha. and got a handy dandy 40a fuse. destroyed the circuit board though. used the brute force method on it. thought thats what was holding the two halves together
edit:
this may be of use to anyone doing this. mine are p49a - dec 2011 from my take of it
I got two of them there! :D There was one left as I walked away and I saw another guy walk up to get it. thanks for the tip on their location, the guy I talked to had no idea where they were.
I have just started tearing apart the plastic carrier, I will add that these cells will also max out my DMM in my septuple XM-L. Now I finally have enough good IMR batteries to power all of my multi-XM-L P60s. ;)
I just have one question because I am curious and don’t have those batteries in my HD’s. Please don’t take this as an opportunity to start a Li-ion safety war. There are plenty of threads going right now for that. I think most here would just assume that type of discussion stay in those threads.
Do the battery packs appear to have cell balancing circuitry? From what I am reading, I’m getting the impression that they don’t. If not, maybe the manufacture used a type of cell that mitigates the risk. If so, those might be some tough cells. Another plus if that is the case.
from what I can tell they are being balance charged, but in packs of2s.not perfect but better than nothing and yes I will be doing a1 amp discharge tonight
Very interested to see the results. Seems if you buy these cells bulk, they are from about $3 up. Couldn’t really find any singles for sale in a quick search last night.
Got to clean up the spot welds tonight and start charging them up.

Looks like everyone’s pestering Scaru, so I’ll add my pester. Love to know at first click whether there is any lumen-output difference in these tool cells as compared to — say — a panasonic 2600 — if Scaru has a minute to try the same in his famous integrated bathroom. In other words, Sanyo 1500 in a light; click it on; take lumen reading. Panasonic in the same light; click it on; take another reading. Are they different? The same? Well, maybe it doesn’t have to be the exact second the light clicks on. Just as long as both readings are taken at the same time in both lights.
At first I thought these produced a dimmer light than a 2600, but after a couple minutes of playing around last night, I’m not so sure. I only tried a couple EDC tube lights. Did anyone else try to see any difference?
I found a couple of these at my hd…what kind of screw driver is used on the outside? don’t want to have to resort to bashing it with a hammer :face_with_monocle:
>>>>>what kind of screw driver is used on the outside?
I believe they’re called Torx security screws or Torx tamper-resistant screws. Torx screws are bad enough trying to find the right-size driver. But these have the added security feature of a raised dot in the screwhead so regular Torx drivers won’t work. I don’t know if HD has these drivers. I got mine on ebay a couple years ago.
I don’t know this seller. Just the first one I ran into. I saw some Torx TR drivers at a mom-and-pop hardware store a couple months ago, so you never know where you’ll find people who want to take apart things they shouldn’t.
